ROLLER-SKATE.

EBPECIIICATION forming part of Letters Patent No. 305,644, dated September 23,, 1884.

Application filed April 18, 1884. (No model.)

' and State ofGonnecticut, have invented a new vIO Improvement in Roller-Skates; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of thisspecification, and represent, in-

Figure 1,a side view of a portion of the footpiece, showing one of the saddles; Fig. 2, a transverse'section through the saddle; Fig. 3, a vertical section at right angles to the section of Fig. 2; Figs. 4., 5, 6, 7, and 8, detached views of the roller, illustrating its construction. l

This'invention relates to an improvement in the construction of roller-skates, with special reference to the method of hanging the rollers, whereby ascertain amount of elasticity is introduced between the axle and the footpiece, and also in the construction of the rollers; and the invention consists in the construction, as hereinafter described, and more particularly recited in the claims.

In illustrating the method of hanging the rollers to the foot-piece I show only a single pair of rollers, or one attachment. It will be understood, however, that this is or may be applied alike to both pairs of rollers.

A represents the foot-piece, of any of the known constructions; B, an inverted -cup shaped socket,which is made fast to the under side of the foot-piece by screws or otherwise,

with-a central hole through it,forming a concave seat, a, on the upper side. Through the foot-piece is a hole, b, corresponding to the seat a 011 the socket. C is the saddle, its head or upper surface corresponding to or some What less than the internal diameter of the socket B, as seen in Fig. 3. In the socket is an india-rubber or other suitable spring, D, upon which the saddle bears. Through the socket a screw, (1, extends into the saddle below, its head a of ball or spherical shape to fit the corresponding seat, a, on the socket. This ball-shaped head and seat permits a universal movement of the saddle,the spring D yielding for such movement, so that the foot may rock to a considerable extent with relation to the rollers. The spring D yields for such movement, and returns the axle toits proper parallelism when at rest. The spring D yields under the 5 5 pressure of the foot and gives an elasticity to the skate, and this elasticity may be reduced by compressing the spring,or vice versa, such compression of the spring being produced by turning the screw d, which the hole 6 1) permits to'be done without removing the socket from the foot-piece. At the lower end the saddle is provided with a transverse bearing, E, for the axle.

To prevent the saddle from rotating onthe 6 screw 01 as a pivot, a lug, F, is formed at diametrically-opposite points on the head of the saddle, which sets into corresponding notches,

G, in the sides of the cup. These notches permit the free play up and down of the saddle, but engage the lugs F, so as to prevent rotation.

My improved roller consists of a hub, f, through which is a corresponding hole to receive the axle, as seen-in Fig. 2. Surrounding this hub and connected to it by a web, 71., is a metal rim, i3, concentric with the axle, and of a diameterlittle less than that of the finished roller. Around this rim, at one end, is a flange, Z, projecting at right angles to theaxis. On the other end are projecting lugs m, here shown as three, set inside the periphery of the rim, as seen in Figs. 4 and 5.

n is a collar corresponding to the fiangel at the opposite end. This collar is recessed on 8 its face, as seen in Fig.6, its internal diameter being so as to set on over the lugs m againstthe end ofthe rim 2', as seen in Fig. 7. From the inside of the recess projections o are formed,

extending inward, leaving a space, 1, between such projections, as seen in Fig. 8, these spaces corresponding to the lugs m, and so that those spaces will permit the collar to pass on over the lugs. In the outer surface of the lugs m is an annular notch, 1", corresponding 5 to the projections 0 on the collar, and so that when the collar is seton over the lugs it may be turned, and so as to bring the projections o into the notches m on the lugs, and thus interlock the, collar with the lugs. The periphery of the roller is composed of rings 8, more or less in number, cut from leather or 5 other suitable material, their internal diameter corresponding to the rim Z, their external diameter little larger than that of the flange Z and collar n. These rings are first set on over the rim '5, against the flange Z, and when the IO requisite number have been applied the collar n is set thereon and forced toward the opas seen in Fig. 7, and the collars have a corresponding notch out upon their inner sur face, so that when set over these ribs the rings cannot turn upon the rim of the roller. By this construction of roller I am enabled to produce a roll presenting a non-metallic surface, the material of which is much thinner than in previous constructions, and therefore less liable to work into irregular shape than where greater depth Orthickness is employed.

I claim 7 1. In aroller-skate, the combination of the foot-piece constructed with a hole, b, vertically through it, the inverted cup-shaped socket B fixed to the under side of the footpiece, the saddle O, the head of which corresponds to the interior of said socket, the said saddle carrying the rollers, the spring D in said socket, the screw d through the hole in the foot-piece and through the socket into the saddle, the under side of the head of the screw spherical, and aseat on the socket of corresponding shape, substantially as and for the purpose described.

2. The combination of the foot-piece A, inverted-cup-shap'ed' socket B, spring D therein, the sides of the socket constructed with a notch, G, the saddle 0, its head corresponding to the spring D, and constructed with a lug, F, corresponding to said notch G, and carrying the rollers, screw -d throughsaid socket into said saddle, whereby the saddle is held in elastic connection with the foot-piece, substantially as described.

3. The herein-described roller for skates, consisting of the metal hub f, the rim Z, and the flange Z on one end of said rim, the. rim connected to the hub,- notched lugs m projecting from the end of the rim opposite the flange, all constructed in one and the same piece, combined with ring-shaped collar against its flange, and the collar forced over the lugs on the opposite end and turned bring theprojection 0 into the notches r, substantially as described. I 4. The herein-described roller for skates, consisting of the metal hub f, the rim Z, and the flange Z on one end of'said rim,the rim connected to the hub, notched lugs m projecting from the end of the rim opposite the flange, all constructed in one and the same piece, combined with the ring-shaped collar n, having projections o and correspondingit, having projections 0' and corresponding notches, '19, upon its inside, and the non-metah lic rings 8, the said rings set upon the rim]
